BACKGROUND OF THE INVENTION

The development of therapeutic agents (e.g., biological drugs) is oftenhampered by short half-lives. The biological half-life or eliminationhalf-life of a substance is the time it takes for a substance (forexample a metabolite, drug, signaling molecule, radioactive nuclide, orother substance) to lose half of its pharmacologic, physiologic, orradiologic activity. As a result of the short half-life, patients areoften administered higher dosages more frequently, which may lead toreduced compliance, higher costs and greater risks of side effects.

Extended-release products are designed to prolong the absorption ofdrugs with short half-lives, thereby allowing longer dosing intervalswhile minimizing fluctuations in serum drug levels. Current strategiesused for extending half-lives are those that increase hydrodynamicvolume (PEGylation) or those that use FcRn-mediated recycling (albuminfusions). Attachment of polypeptides or lipophilic constituents to drugshas also been used to extend the half-life of a biological agent (U.S.Pat. Nos. 6,268,343; 5,750,497; 8,129,343).

Exemplarycompositions are suitable for injection or infusion into an animal byany route available to the skilled worker, such as intraarticular,subcutaneous, intravenous, intramuscular, intraperitoneal, intracerebral(intraparenchymal), intracerebroventricular, intramuscular, intraocular,intraarterial, or intralesional routes. A parenteral formulationtypically may be a sterile, pyrogen-free, isotonic aqueous solution,optionally containing pharmaceutically acceptable preservatives.

See generally, Remington's Pharmaceutical Science,16th Ed., Mack Eds., 1980.

Pharmaceutical compositions described herein may be formulated forcontrolled or sustained delivery in a manner that provides localconcentration of the product (e.g., bolus, depot effect) and/orincreased stability or half-life in a particular local environment. Thecompositions can include the formulation of mTAs, PLCs, polypeptides,nucleic acids, or vectors disclosed herein with particulate preparationsof polymeric compounds such as polylactic acid, polyglycolic acid, etc.,as well as agents such as a biodegradable matrix, injectablemicrospheres, microcapsular particles, microcapsules, bioerodibleparticles beads, liposomes, and implantable delivery devices thatprovide for the controlled or sustained release of the active agentwhich then can be delivered as a depot injection. Techniques forformulating such sustained- or controlled-delivery means are known and avariety of polymers have been developed and used for the controlledrelease and delivery of drugs. Such polymers are typically biodegradableand biocompatible. Polymer hydrogels, including those formed bycomplexation of enantiomeric polymer or polypeptide segments, andhydrogels with temperature or pH sensitive properties, may be desirablefor providing drug depot effect because of the mild and aqueousconditions involved in trapping bioactive protein agents (e.g.,antibodies comprising an ultralong CDR3). See, for example, thedescription of controlled release porous polymeric microparticles forthe delivery of pharmaceutical compositions in WO 93/15722.

Suitable materials for this purpose include polylactides (see, e.g.,U.S. Pat. No. 3,773,919), polymers of poly-(a-hydroxycarboxylic acids),such as poly-D-(−)-3-hydroxybutyric acid (EP 133,988A), copolymers ofL-glutamic acid and gamma ethyl-L-glutamate (Sidman et al., Biopolymers,22: 547-556 (1983)), poly(2-hydroxyethyl-methacrylate) (Langer et al.,J. Biomed. Mater. Res., 15: 167-277 (1981), and Langer, Chem. Tech., 12:98-105 (1982)), ethylene vinyl acetate, or poly-D(−)-3-hydroxybutyricacid. Other biodegradable polymers include poly(lactones),poly(acetals), poly(orthoesters), and poly(orthocarbonates).Sustained-release compositions also may include liposomes, which can beprepared by any of several methods known in the art (see, e.g., Eppsteinet al., Proc. Natl. Acad. Sci. USA, 82: 3688-92 (1985)). The carrieritself, or its degradation products, should be nontoxic in the targettissue and should not further aggravate the condition. This can bedetermined by routine screening in animal models of the target disorderor, if such models are unavailable, in normal animals.

Microencapsulation of recombinant proteins for sustained release hasbeen performed successfully with human growth hormone (rhGH),interferon-(rhIFN-), interleukin-2, and MN rgp120. Johnson et al., Nat.Med., 2:795-799 (1996); Yasuda, Biomed. Ther., 27:1221-1223 (1993); Horaet al., Bio/Technology. 8:755-758 (1990); Cleland, “Design andProduction of Single Immunization Vaccines Using PolylactidePolyglycolide Microsphere Systems,” in Vaccine Design: The Subunit andAdjuvant Approach, Powell and Newman, eds, (Plenum Press: New York,1995), pp. 439-462; WO 97/03692, WO 96/40072, WO 96/07399; and U.S. Pat.No. 5,654,010. The sustained-release formulations of these proteins weredeveloped using poly-lactic-coglycolic acid (PLGA) polymer due to itsbiocompatibility and wide range of biodegradable properties. Thedegradation products of PLGA, lactic and glycolic acids can be clearedquickly within the human body. Moreover, the degradability of thispolymer can be depending on its molecular weight and composition. Lewis,“Controlled release of bioactive agents from lactide/glycolide polymer,”in: M. Chasin and R. Langer (Eds.), Biodegradable Polymers as DrugDelivery Systems (Marcel Dekker: New York, 1990), pp. 1-41. Additionalexamples of sustained release compositions include, for example, EP58,481A, U.S. Pat. No. 3,887,699, EP 158,277A, Canadian Patent No.1176565, U. Sidman et al., Biopolymers 22, 547 [1983], R. Langer et al.,Chem. Tech. 12, 98 [1982], Sinha et al., J. Control. Release 90, 261[2003], Zhu et al., Nat. Biotechnol. 18, 24 [2000], and Dai et al.,Colloids Surf B Biointerfaces 41, 117 [2005].

Bioadhesive polymers are also contemplated for use in or withcompositions of the present disclosure. Bioadhesives are synthetic andnaturally occurring materials able to adhere to biological substratesfor extended time periods. For example, Carbopol and polycarbophil areboth synthetic cross-linked derivatives of poly(acrylic acid).Bioadhesive delivery systems based on naturally occurring substancesinclude for example hyaluronic acid, also known as hyaluronan.Hyaluronic acid is a naturally occurring mucopolysaccharide consistingof residues of D-glucuronic and N-acetyl-D-glucosamine. Hyaluronic acidis found in the extracellular tissue matrix of vertebrates, including inconnective tissues, as well as in synovial fluid and in the vitreous andaqueous humor of the eye. Esterified derivatives of hyaluronic acid havebeen used to produce microspheres for use in delivery that arebiocompatible and biodegradable (see, for example, Cortivo et al.,Biomaterials (1991) 12:727-730; EP 517,565; WO 96/29998; Illum et al.,J. Controlled Rel. (1994) 29:133-141).

Both biodegradable and non-biodegradable polymeric matrices may be usedto deliver compositions of the present disclosure, and such polymericmatrices may comprise natural or synthetic polymers. Biodegradablematrices are preferred. The period of time over which release occurs isbased on selection of the polymer. Typically, release over a periodranging from between a few hours and three to twelve months is mostdesirable. Exemplary synthetic polymers which may be used to form thebiodegradable delivery system include: polymers of lactic acid andglycolic acid, polyamides, polycarbonates, polyalkylenes, polyalkyleneglycols, polyalkylene oxides, polyalkylene terepthalates, polyvinylalcohols, polyvinyl ethers, polyvinyl esters, poly-vinyl halides,polyvinylpyrrolidone, polyglycolides, polysiloxanes, polyanhydrides,polyurethanes and co-polymers thereof, poly(butic acid), poly(valericacid), alkyl cellulose, hydroxyalkyl celluloses, cellulose ethers,cellulose esters, nitro celluloses, polymers of acrylic and methacrylicesters, methyl cellulose, ethyl cellulose, hydroxypropyl cellulose,hydroxypropyl methyl cellulose, hydroxybutyl methyl cellulose, celluloseacetate, cellulose propionate, cellulose acetate butyrate, celluloseacetate phthalate, carboxyethyl cellulose, cellulose triacetate,cellulose sulphate sodium salt, poly(methyl methacrylate), poly(ethylmethacrylate), poly(butylmethacrylate), poly(isobutyl methacrylate),poly(hexylmethacrylate), poly(isodecyl methacrylate), poly(laurylmethacrylate), poly(phenyl methacrylate), poly(methyl acrylate),poly(isopropyl acrylate), poly(isobutyl acrylate), poly(octadecylacrylate), polyethylene, polypropylene, poly(ethylene glycol),poly(ethylene oxide), poly(ethylene terephthalate), poly(vinylalcohols), polyvinyl acetate, poly vinyl chloride, polystyrene andpolyvinylpyrrolidone.

In general, thesematerials degrade either by enzymatic hydrolysis or exposure to water invivo, by surface or bulk erosion. The polymer optionally is in the formof a hydrogel (see, for example, WO 04/009664, WO 05/087201, Sawhney, etal., Macromolecules, 1993, 26, 581-587) that can absorb up to about 90%of its weight in water and further, optionally is cross-linked withmulti-valent ions or other polymers.

Alternatively or additionally, the compositions may be administeredlocally via implantation into the affected area of a membrane, sponge,or other appropriate material on to which a PLC, mTA, nucleic acid, orvector disclosed herein has been absorbed or encapsulated. Where animplantation device is used, the device may be implanted into anysuitable tissue or organ, and delivery of an antibody comprising anultralong CDR3 antibody fragment, nucleic acid, or vector disclosedherein can be directly through the device via bolus, or via continuousadministration, or via catheter using continuous infusion.

A pharmaceutical composition comprising a PLC, mTA, nucleic acid, orvector disclosed herein may be formulated for inhalation, such as forexample, as a dry powder. Inhalation solutions also may be formulated ina liquefied propellant for aerosol delivery. In yet another formulation,solutions may be nebulized. Additional pharmaceutical composition forpulmonary administration include, those described, for example, in WO94/20069, which discloses pulmonary delivery of chemically modifiedproteins. For pulmonary delivery, the particle size should be suitablefor delivery to the distal lung. For example, the particle size may befrom 1 μm to 5 μm; however, larger particles may be used, for example,if each particle is fairly porous.

Certain formulations containing antibodies comprising a PLC, mTA,nucleic acid, or vector disclosed herein may be administered orally.Formulations administered in this fashion may be formulated with orwithout those carriers customarily used in the compounding of soliddosage forms such as tablets and capsules. For example, a capsule can bedesigned to release the active portion of the formulation at the pointin the gastrointestinal tract when bioavailability is maximized andpre-systemic degradation is minimized. Additional agents may be includedto facilitate absorption of a selective binding agent. Diluents,flavorings, low melting point waxes, vegetable oils, lubricants,suspending agents, tablet disintegrating agents, and binders also can beemployed.

By dissolving the tablets in sterile water, or anotherappropriate vehicle, solutions may be prepared in unit dose form.Suitable excipients include, but are not limited to, inert diluents,such as calcium carbonate, sodium carbonate or bicarbonate, lactose, orcalcium phosphate; or binding agents, such as starch, gelatin, oracacia; or lubricating agents such as magnesium stearate, stearic acid,or talc.

Suitable and/or preferred pharmaceutical formulations may be determinedin view of the present disclosure and general knowledge of formulationtechnology, depending upon the intended route of administration,delivery format, and desired dosage. Regardless of the manner ofadministration, an effective dose may be calculated according to patientbody weight, body surface area, or organ size. Further refinement of thecalculations for determining the appropriate dosage for treatmentinvolving each of the formulations described herein are routinely madein the art and is within the ambit of tasks routinely performed in theart. Appropriate dosages may be ascertained through use of appropriatedose-response data.

Vectors, Host Cells and Recombinant Methods

A TA, as disclosed herein, may be expressed by recombinant methods.Generally, a nucleic acid encoding a TA may be isolated and insertedinto a replicable vector for further cloning (amplification of the DNA)or for expression. DNA encoding the TA may be prepared by PCRamplification and sequenced using conventional procedures (e.g., byusing oligonucleotide probes that are capable of binding specifically tonucleotides encoding a TA). In an exemplary embodiment, nucleic acidencoding a TA is PCR amplified, restriction enzyme digested and gelpurified. The digested DNA may be inserted into a replicable vector. Thereplicable vector containing the digested DNA insertion may betransformed or transduced into a host cell for further cloning(amplification of the DNA) or for expression. Host cells may beprokaryotic or eukaryotic cells.

Polynucleotide sequences encoding polypeptide components of the mTAs orPLCs disclosed herein may be obtained by PCR amplification withoverlapping oligonucleotide primers. Polynucleotide sequences may beisolated and sequenced from TA producing cells. Alternatively,polynucleotides may be synthesized using nucleotide synthesizer or PCRtechniques. Once obtained, sequences encoding the polypeptides areinserted into a recombinant vector capable of replicating and expressingheterologous polynucleotides in prokaryotic and/or eukaryotic hosts.

In addition, phage vectors containing replicon and control sequencesthat are compatible with the host microorganism may be used astransforming vectors in connection with these hosts. For example,bacteriophage such as λGEM™-11 may be utilized in making a recombinantvector which can be used to transform susceptible host cells such as E.coli LE392.

TAs may be expressed in intracellularly (e.g., cytoplasm) orextracellularly (e.g., secretion). For extracellular expression, thevector may comprise a secretion signal which enables translocation ofthe TA to the outside of the cell.

Suitable host cells for cloning or expression of TA-encoding vectorsinclude prokaryotic or eukaryotic cells. The host cell may be aeukaryotic. Examples of eukaryotic cells include, but are not limitedto, Human Embryonic Kidney (HEK) cell, Chinese Hamster Ovary (CHO) cell,fungi, yeasts, invertebrate cells (e.g., plant cells and insect cells),lymphoid cell (e.g., YO, NSO, Sp20 cell). Other examples of suitablemammalian host cell lines are monkey kidney CV1 line transformed by SV40(COS-7); baby hamster kidney cells (BHK); mouse Sertoli cells; monkeykidney cells (CV1); African green monkey kidney cells (VERO-76); humancervical carcinoma cells (HELA); canine kidney cells (MDCK; buffalo ratliver cells (BRL 3A); human lung cells (W138); human liver cells(HepG2); mouse mammary tumor (MMT 060562); TR1 cells; MRC 5 cells; andFS4 cells. The host cell may be a prokaryotic cell (e.g., E. coli).

Host cells may be transformed with vectors containing nucleotidesencoding a TA. Transformed host cells may be cultured in media. Themedia may be supplemented with one or more agents for inducingpromoters, selecting transformants, or amplifying or expressing thegenes encoding the desired sequences. Methods for transforming hostcells are known in the art and may include electroporation, calciumchloride, or polyethylene glycol/DMSO.

Alternatively, host cells may be transfected or transduced with vectorscontaining nucleotides encoding a TA. Transfected or transduced hostcells may be cultured in media. The media may be supplemented with oneor more agents for inducing promoters, selecting transfected ortransduced cells, or expressing genes encoding the desired sequences.

The expressed TAs may be secreted into and recovered from the periplasmof the host cells or transported into the culture media. Proteinrecovery from the periplasm may involve disrupting the host cell.Disruption of the host cell may comprise osmotic shock, sonication orlysis. Centrifugation or filtration may be used to remove cell debris orwhole cells. The TAs may be further purified, for example, by affinityresin chromatography.

Alternatively, TAs that are secreted into the culture media may beisolated therein. Cells may be removed from the culture and the culturesupernatant being filtered and concentrated for further purification ofthe proteins produced. The expressed polypeptides can be furtherisolated and identified using commonly known methods such aspolyacrylamide gel electrophoresis (PAGE) and Western blot assay.

TA production may be conducted in large quantity by a fermentationprocess. Various large-scale fed-batch fermentation procedures areavailable for production of recombinant proteins. Large-scalefermentations have at least 1000 liters of capacity, preferably about1,000 to 100,000 liters of capacity. These fermentors use agitatorimpellers to distribute oxygen and nutrients, especially glucose (apreferred carbon/energy source). Small scale fermentation refersgenerally to fermentation in a fermentor that is no more thanapproximately 100 liters in volumetric capacity, and can range fromabout 1 liter to about 100 liters.

In a fermentation process, induction of protein expression is typicallyinitiated after the cells have been grown under suitable conditions to adesired density, e.g., an OD550 of about 180-220, at which stage thecells are in the early stationary phase. A variety of inducers may beused, according to the vector construct employed, as is known in the artand described above. Cells may be grown for shorter periods prior toinduction. Cells are usually induced for about 12-50 hours, althoughlonger or shorter induction time may be used.

To improve the production yield and quality of the TAs disclosed herein,various fermentation conditions can be modified. For example, to improvethe proper assembly and folding of the secreted TA polypeptides,additional vectors overexpressing chaperone proteins, such as Dsbproteins (DsbA, DsbB, DsbC, DsbD and or DsbG) or FkpA (a peptidylprolylcis,trans-isomerase with chaperone activity) may be used to co-transformthe host prokaryotic cells. The chaperone proteins have beendemonstrated to facilitate the proper folding and solubility ofheterologous proteins produced in bacterial host cells.

To minimize proteolysis of expressed heterologous proteins (especiallythose that are proteolytically sensitive), certain host strainsdeficient for proteolytic enzymes can be used for the presentdisclosure. For example, host cell strains may be modified to effectgenetic mutation(s) in the genes encoding known bacterial proteases suchas Protease III, OmpT, DegP, Tsp, Protease I, Protease Mi, Protease V,Protease VI and combinations thereof. Some E. coli protease-deficientstrains are available.

Standard protein purification methods known in the art can be employed.The following procedures are exemplary of suitable purificationprocedures: fractionation on immunoaffinity or ion-exchange columns,ethanol precipitation, reverse phase HPLC, chromatography on silica oron a cation-exchange resin such as DEAE, chromatofocusing, SDS-PAGE,ammonium sulfate precipitation, hydroxylapatite chromatography, gelelectrophoresis, dialysis, and affinity chromatography and gelfiltration using, for example, Sephadex G-75.

TAs may be concentrated using a commercially available proteinconcentration filter, for example, an Amicon or Millipore Pellicon®ultrafiltration unit.

Protease inhibitors or protease inhibitor cocktails may be included inany of the foregoing steps to inhibit proteolysis of the TA.

In some cases, a TA or fragment thereof may not be biologically activeupon isolation. Various methods for “refolding” or converting apolypeptide to its tertiary structure and generating disulfide linkages,can be used to restore biological activity. Such methods includeexposing the solubilized polypeptide to a pH usually above 7 and in thepresence of a particular concentration of a chaotrope. The selection ofchaotrope is very similar to the choices used for inclusion bodysolubilization, but usually the chaotrope is used at a lowerconcentration and is not necessarily the same as chaotropes used for thesolubilization. In most cases the refolding/oxidation solution will alsocontain a reducing agent or the reducing agent plus its oxidized form ina specific ratio to generate a particular redox potential allowing fordisulfide shuffling to occur in the formation of the protein's cysteinebridge(s). Some of the commonly used redox couples includecystein/cystamine, glutathione (GSH)/dithiobis GSH, cupric chloride,dithiothreitol (DTT)/dithiane DTT, and 2-mercaptoethanol (bME)/di-thio-b(ME). In many instances, a cosolvent may be used to increase theefficiency of the refolding, and common reagents used for this purposeinclude glycerol, polyethylene glycol of various molecular weights,arginine and the like.

Unless otherwise noted,heterocycloalkyls have from 2 to 10 carbons in the ring. It isunderstood that when referring to the number of carbon atoms in aheterocycloalkyl, the number of carbon atoms in the heterocycloalkyl isnot the same as the total number of atoms (including the heteroatoms)that make up the heterocycloalkyl (i.e. skeletal atoms of theheterocycloalkyl ring). Unless stated otherwise specifically in thespecification, a heterocycloalkyl group may be optionally substituted.

The term “heteroaryl” as used herein, alone or in combination, refers tooptionally substituted aromatic monoradicals containing from about fiveto about twenty skeletal ring atoms, where one or more of the ring atomsis a heteroatom independently selected from among oxygen, nitrogen,sulfur, phosphorous, silicon, selenium and tin but not limited to theseatoms and with the proviso that the ring of said group does not containtwo adjacent O or S atoms. In embodiments in which two or moreheteroatoms are present in the ring, the two or more heteroatoms can bethe same as each another, or some or all of the two or more heteroatomscan each be different from the others. The term heteroaryl includesoptionally substituted fused and non-fused heteroaryl radicals having atleast one heteroatom. The term heteroaryl also includes fused andnon-fused heteroaryls having from five to about twelve skeletal ringatoms, as well as those having from five to about ten skeletal ringatoms.

All the above groups may be either substituted or unsubstituted. Theterm “substituted” as used herein means any of the above groups (e.g.,alkyl, alkylene, alkoxy, aryl, cycloalkyl, haloalkyl, heterocyclyland/or heteroaryl) may be further functionalized wherein at least onehydrogen atom is replaced by a bond to a non-hydrogen atom substituent.Unless stated specifically in the specification, a substituted group mayinclude one or more substituents selected from: oxo, amino, —CO₂H,nitrile, nitro, hydroxyl, thiooxy, alkyl, alkylene, alkoxy, aryl,cycloalkyl, heterocyclyl, heteroaryl, di alkylamines, arylamines,alkylarylamines, diarylamines, trialkylammonium (—N⁺R₃), N-oxides,imides, and enamines; a silicon atom in groups such as trialkylsilylgroups, dialkylarylsilyl groups, alkyldiarylsilyl groups, triarylsilylgroups, perfluoroalkyl or perfluoroalkoxy, for example, trifluoromethylor trifluoromethoxy. “Substituted” also means any of the above groups inwhich one or more hydrogen atoms are replaced by a higher-order bond(e.g., a double- or triple-bond) to a heteroatom such as oxygen in oxo,carbonyl, carboxyl, and ester groups; and nitrogen in groups such asimines, oximes, hydrazones, and nitriles. For example, “substituted”includes any of the above groups in which one or more hydrogen atoms arereplaced

with —NH₂, —NR_(g)C(═O)NR_(g)R_(h), —NR_(g)C(═O)OR_(h), —NR_(g)SO₂R_(h),—OC(═O)NR_(g)R_(h), —OR_(g), —SR_(g), —SOR_(g), —SO₂R_(g), —OSO₂R_(g),—SO₂OR_(g), ═NSO₂R_(g), and —SO₂NR_(g)R_(h). In the foregoing, R_(g) andR_(h) are the same or different and independently hydrogen, alkyl,alkoxy, alkylamino, thioalkyl, aryl, aralkyl, cycloalkyl,cycloalkylalkyl, haloalkyl, heterocyclyl, N-heterocyclyl,heterocyclylalkyl, heteroaryl, N-heteroaryl and/or heteroarylalkyl. Inaddition, each of the foregoing substituents may also be optionallysubstituted with one or more of the above substituents. Furthermore, anyof the above groups may be substituted to include one or more internaloxygen, sulfur, or nitrogen atoms. For example, an alkyl group may besubstituted with one or more internal oxygen atoms to form an ether orpolyether group. Similarly, an alkyl group may be substituted with oneor more internal sulfur atoms to form a thioether, disulfide, etc.

The term “optional” or “optionally” means that the subsequentlydescribed event or circumstance may or may not occur, and that thedescription includes instances where said event or circumstance occursand instances in which it does not. For example, “optionally substitutedalkyl” means either “alkyl” or “substituted alkyl” as defined above.Further, an optionally substituted group may be un-substituted (e.g.,—CH₂CH₃), fully substituted (e.g., —CF₂CF₃), mono-substituted (e.g.,—CH₂CH₂F) or substituted at a level anywhere in-between fullysubstituted and mono-substituted (e.g., —CH₂CHF₂, —CH₂CF₃, —CF₂CH₃,—CFHCHF₂, etc). It will be understood by those skilled in the art withrespect to any group containing one or more substituents that suchgroups are not intended to introduce any substitution or substitutionpatterns (e.g., substituted alkyl includes optionally substitutedcycloalkyl groups, which in turn are defined as including optionallysubstituted alkyl groups, potentially ad infinitum) that are stericallyimpractical and/or synthetically non-feasible. Thus, any substituentsdescribed should generally be understood as having a maximum molecularweight of about 1,000 daltons, and more typically, up to about 500daltons.

A “tautomer” refers to a proton shift from one atom of a molecule toanother atom of the same molecule. The compounds presented herein mayexist as tautomers. Tautomers are compounds that are interconvertible bymigration of a hydrogen atom, accompanied by a switch of a single bondand adjacent double bond. In bonding arrangements where tautomerizationis possible, a chemical equilibrium of the tautomers will exist. Alltautomeric forms of the compounds disclosed herein are contemplated.

Thus, enzymes mayproduce specific structural alterations to a compound. For example,cytochrome P450 catalyzes a variety of oxidative and reductive reactionswhile uridine diphosphate glucuronyl transferases catalyze the transferof an activated glucuronic-acid molecule to aromatic alcohols, aliphaticalcohols, carboxylic acids, amines and free sulfhydryl groups. Furtherinformation on metabolism may be obtained from The Pharmacological Basisof Therapeutics, 9th Edition, McGraw-Hill (1996). Metabolites of thecompounds disclosed herein can be identified either by administration ofcompounds to a host and analysis of tissue samples from the host, or byincubation of compounds with hepatic cells in vitro and analysis of theresulting compounds. Both methods are well known in the art. Metabolitesof a compound may be formed by oxidative processes and correspond to thecorresponding hydroxy-containing compound. A compound may be metabolizedto one or more pharmacologically active metabolites.

Chronic effect on body weight loss with dailyadministration of mTA4 or mTA37 for 5 weeks and cumulative food intakefor 2 weeks are shown in FIG. 15. Increased intra-peritoneal glucosetolerance after daily administration of mTA4 or mTA37 for 5 weeks isshown in FIG. 16. Reduced fasting blood glucose levels after dailyadministration of mTA4 or mTA37 for 5 weeks is shown in FIG. 17.

Example 16. Cholesterol Level Determination

Collected plasma was used for cholesterol level determination accordingto the manufacturer's guide (cholesterol assay kit, Abcam, Cambridge,England). Briefly, plasma was diluted using cholesterol assay buffer andthen reacted with same volume of reaction mix containing cholesterolassay buffer, cholesterol probe, enzyme mix and cholesterol esterase.After incubation at 37° C. for 1 hour, the absorbance at 560 nm wasmeasured using an Envision multilabel plate reader (PerkinElmer,Waltham, Mass.). Subsequently, the concentration of cholesterol inplasma was calculated using a standard curve.

Exemplary data for select mTAs is shown in FIG. 18B. There was decreasedcholesterol level in plasma after daily administration of mTA4 or mTA37for 5 weeks.

Example 17. Triglyceride Level Measurement

Collected plasma was again used for triglyceride level determinationusing a triglyceride colorimetric assay kit (Cayman chemical, Ann Arbor,Mich.). 5 μL of plasma samples or standard were added into a 384 wellplate and followed by adding 75 μL of diluted enzyme buffer to eachwell. The plate was incubated at room temperature for 15 min, and theabsorbance was read at 560 nm using an Envision multilabel plate reader(PerkinElmer, Waltham, Mass.). Again, the concentration of triglyceridein plasma was calculated using a standard curve.

Exemplary data for select mTAs is shown in FIG. 18A. There was decreasedtriglyceride level in plasma after daily administration of mTA4 or mTA37for 5 weeks.

Example 18. Oil Red O Staining (Lipid Droplet Staining)

Frozen tissue sections of liver were cut at 10 μm and air dried to theslides. After fixation in 10% formalin for 5 min, the slides werebriefly washed with running tap water for 10 min, followed by rinse with60{circumflex over ( )}isopropanol. Subsequently, oil red O workingsolution (0.3% oil red O) was used for lipid staining for 15 min. Slideswere again rinsed with 60% isopropanol and then nuclei were lightlystained with alum haematoxylin, followed by rinse with distilled waterand mounted in glycerine jelly. After half an hour, pictures were takenunder microscopy.

Exemplary data are shown in FIG. 19, in which reduced lipid dropletamounts were observed after daily administration of mTA4 or mTA37 for 5weeks.

Example 19. Application of Micro-Needle Based Patch on Guinea Pigs

Microneedle patch based transdermal drug delivery was performed usingguinea pigs. Guinea pigs were shaved one day before patch application.On the second day, micro-needle based patches were applied onto theanimal skin for 5 min and blood was extracted at different time points(5 min, 30 min, 1 h, 2 h, 3 h, 5 h, 8 h, 24 h, 32 h, 48 h, 72 h).Peptide concentration at each time point was determined using the samemethod (functional activity assay) as described above. Transdermalbioavailability (F) was calculated as the ratio of area under the curve(AUC) between microneedle patch application and i.v. injection groups.

Exemplary data are shown in FIGS. 20-22. Pharmacokinetic profiles ofmTA4 after i.v. or s.c. injection or micro-needle based transdermaldelivery are shown in FIG. 20. Blood glucose curves and AUC values froman oral glucose tolerance test at 24 h, 48 h, and 96 h after mTAadministration through micro-needle based transdermal delivery are shownin FIGS. 21 and 22.

Example 20. Murine Model of Ulcerative Colitis (DSS Model)

Colitis in mouse was induced by adding 3% DSS (dextran sulfate sodium)in the drinking water for 12 consecutive days. Besides DSS placement,mice were daily treated with GLP-2 analogs (40 μg/kg/day) [GLP-2G is theGLP2 sequence with G2S mutation and is a known drug called teduglutide].Cyclosporine A (20 mg/kg/day) was used for the positive control groupand PBS for the negative control group. During the experiment period,body weight was measured every day.

Intestinal Weight/Body Weight Measurement

Animals were sacrificed after 12 days of treatment. Small intestine wasimmediately excited and flushed with PBS. After PBS was gently squishedout, intestinal weight was weighed using an analytical balance.Intestinal vs. body weight ratio was then calculated and analyzed.

Body weight and intestine weight versus body weight in DSS-inducedcolitis mice after daily administration of mTA68 for 12 days are shownin FIG. 23.
